<font face="Times New Roman, Times, serif"> This is </font>just
basic fundamentals and has nothing to do with eQuest. If you have 50
rooms, and want perfect control in each one you need 50 t-stats and 50
PSZ units. Once you move away from this you need a way to
independently manipulate the temperature in each room up and down. VFD
will vary volume and pressure, but will not independently vary the
volume to an individual room as you are using them. There are many
ways to do this, VAV, terminal units, multi-zones. Either your concept
of the design or the design itself is flawed. Either way there is no
point doing any more work with eQuest until you resolve the design
problem. Equest is working fine and your results are totally
expected. I rarely open files, I do not have time, but more
specifically there is no point in your case. You have junk going in,
therefore you have junk coming out.<br>
Dakota has done you a big favour, much more eloquent than I and
given some excellent pointers. You need to pick up the phone and nail
down the basics and don't forget to ask about the outside air. VAV and
OA don't always play well together. You will also have rooms with 35
kids and a room with one principal.<br>
Sorry about the touch of flame but much of the debate on this site
lately has regressed to teaching of basic concepts or to users who seem
to have only spent a week or 2 in the trenches. It seems some of the
old hands are getting cranky because the privilege of asking questions
on this site is getting abused.<br>

style="font-family: Arial; color: navy; font-size: 10pt;">Have posted
the proposed and the baseline case model on behalf of Adam, also
responding to your query about VFD, about varying the flows, do we need
to model a vav system?.. or I am not very familiar with this part as
the specs don’t show VAV terminal units, they have provided the VFD
schedules. It would really help if you could let us know how to to
rectify the error. I also went ahead and changed the hot deck
temperature to default as suggested by you and Demba. But it doesn’t
seem to help much </span></font></p>
